IMPROVEMENT .IN VALVES FOR VARNISH AND OTHER CANS OR VESKSELS.

Specification forming part of Letters Patent No. 178,601, dated June 13,1876; application filed November 12, 1875.

' To all 'whom tt may concern.-

molasses, or other materials, have been pro-V vided with a hole near thebottom, into which is screwed a gate or stop-cock. There is difiiculty,however, in transporting these vessels with the gate attached, becausethe latter projects and is liable to injury.

My invention relates to a peculiar construction of valve or gate,especially adapted` to being applied at the inner end of thescrew-socket, so that it can be opened or closed, as required,independent of the outer faucet hence this valve will be used inshipping the can of varnish, oil, or other liquid, and partially orentirely opened after the usual faucet is screwed `to place. Thisbecomes an additional protection against leakage or accident, and thisvalve can be closed when the can is being refilled, to prevent sedimentpassing into the outer faucet.

In the drawing, Figure l is a section of the socket and gates as readyfor use. Fig. 2 is an elevation of the inner gate as open. Fig. 3 is aplan of the improved gate for the inner end of the socket.

The socket a is made with la screw-thread in the inside, and with aflange, b, upon the outside.- With metal cans or vessels this socketwill be soldered permanently in place. With wooden cans or "essels thissocket will be driven into place, and the inner valve or gate, whenscrewed to place, will clamp the wood.

ver-arm la isprovided with' an attaching pivot-stud, r, and abearing-block, s, resting upon the surface of the face-plate e at theopposite side of the fulcrum-pivot r to the valve d, so that more orless pressure can be applied to the valve by the screw 6. The projectiont, between the stops 7L h upon c, limits the swinging movement of theleverarm k', and the face-plate c is extended at one side of the openingto the thimble z' suffioiently to form a bearing for the valve d when itis turned aside from over the opening.

By this construction the valve d is free to revolve and to accommodateitself to its seat, and it cannot become misplaced, because it alwaysrests against the at surface of the face-plate, whether open or closed.

In consequence of the valve being circular and free to turn, as it maybe moved bodily aside, there is less risk than heretofore of the face ofthe valve becoming grooved and cut by foreign substances, because thevalve will turn around if there is any obstruction to the movement ofany part of its surface, and in so doing that obstruction will generallybe dislodged.

The rod 7c, extending from the arm 7c to the bung-hole or top of thecan, allows the valve tobe operated at any time, for the purposesaforesaid.

The tube Z and gate m are of any usual construction, and this tube Z isof a size to screw i into the socket a hence this gate l m can bcremoved or attached to the socket a with facility when the gate d isclosed, and this gate d is entirely out of the way, and can be opened orclosed by the rod k, as occasion may require. v

This improvement gives great security in case of lire, because it willretain the contents, even if the outer faucet is broken ott'. Thepressure of the liquid tends to make the inner valve or gate tight.

By closing the inner gate before refilling a can, sediment is excludedfrom the outer gate,

and the inner gate. can be opened after the.

foreign matters have subsided. .and by opening the inner gate more orless, the rush of liquid through the outer gate is regulated.

I claim as my inventionl.
